WASHER AND GASKET CUTTER.

To all whom it may concern:

Be it known that I, JAMns A. ROSE, a citizen of the United States,residing at Eastings, in the county of Adams and State of Nebraska, haveinvented a new and useful lVasher and Gasket Cutter, of which thefollowing is a specification.

The invention relates to improvements in washer and gasket cutters.

The object of the present invention is to improve the construction ofwasher and gasket cutters, more especially that shown and described inLetters Patent, No. 692,712, dated Feb. 4, 1902, and to provide a simpleand comparatively inexpensive washer and gasket cutter, designed foroperating on all kinds of sheet packing and provided with means forautomatically feeding the knife into the material and for holding thelatter while it is being cut.

lVith these and other objects in View, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing.Figure 1 is a perspective view of a washer and gasketcutter, constructed in accordance with this invention. Fig. 2 is avertical sectional view of the same.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

The frame of the machine, like that of the said patent, is equipped witha circular base 1 and is provided with a horizontal top 2, supported byvertical rods or posts 3. The top of the frame is provided with acentral opening receiving a vertical bearing sleeve 1, projecting fromthe upper face of the top, and depending below the lower face of thesame, and provided with an intermediate annular flange or collar 5,which is secured to the top 2 of the frame at the upper face thereof bymeans of rivets, or other suitable fastening devices. The sleeve forms abearing for a vertical shaft 6, provided at its upper end with anoperating arm 7 and having an interiorly threaded vertical socket 8 atits lower end. The operating arm 7 is Specification of Letters Patent.

provided at its outer end with a suitable pivoted knob or handle 9,forming a crank handle and adapted to be grasped by the operator, butany other suitable operating means may be employed for rotating theshaft 6.

The shaft 6 carries in its rotary movement a graduated knife supportingarm 10, arranged horizontally and adjustably secured to the lower end ofthe shaft 6 by means of a clamping member 11, provided with a slot toreceive the graduated arm 10, and having a reduced threaded upperportion 12, which fits within and engages the threads of the socket S ofthe lower end of the vertical shaft. The shaft and the clamping memberare readily adjusted by rotating the former, and the forward rotarymovement of the shaft incident to the operation of the device serves tohold the lower end of the shaft and the clamping member tightly inengagement with the graduated arm. The shaft is rotated backwardly withrespect to the graduated arm to release the latter, the arm beingpreferably held stationary for such purpose. The clamping member 11,which forms a continuation or lower section of the shaft, is provided atits lower end with a depending centering point 13, which is arranged topierce the material operated on by the device.

The knife carrying arm 10, which is equipped with a scale 14, isprovided near its outer end with a vertical opening 15 of rectangularform to receive a squared knife 16, which is slidable vertically in therectangular opening. The knife is fed downwardly by the meanshereinafter described to force its lower cutting portion 17 into thematerial, whereby the latter is accurately, gradually and easily cut bythe device. T he material is held during the cutting operation by arotary wheel 18, located adjacent to and beyond the knife 16 and mountedon a reduced pivot portion 19 of the outer end of the graduated arm 10.The wheel, which is constructed of steel, or other suitable material, isretained on the pivot or spindle of the arm by means of a suitablefastening device, and it is arranged to run on the upper face of thematerial contiguous to the knife, and it holds the material firmlyagainst the supporting surface while the material is being cut by theknife.

The knife is automatically fed downwardly during the rotary movement ofthe shaft 6 by means of a vertical adjusting screw 20, mounted in athreaded perforation 21 of the graduated arm and provided at the upperend with a horizontal head 22, forming the body portion of a tappet orfeed wheel and fitting against the upper end of the knife and adapted tomove the same downward. The head of the adjusting screw is provided withradially arranged horizontally disposed tappet arms 23, adapted to beengaged by an actuating member 24, ar ranged in the path of the arms anddepending from the top of the frame. At each revolution of the shaft,one of the arms of the feed or tappet wheel comes in contact with therelatively fixed actuating member 24:, and is oscillated by the samethereby ro tating the adjusting screw and moving the same downward. riesthe knife with it in its downward movement and feeds the knife into thematerial. This operation is repeated until the washer and gasket issevered from the rest of the material.

The top of the frame is provided with two radially arranged rows ofperforations 25, the perforation of one row being located at intervalsbetween the perforations of the other row to secure a fine adjustment.These perforations are adapted to receive the removable pin or member24:, which may be placed in any of the said perforations. The pin isprovided at its upper end with a suitable head, which is supported bythe top of the frame. The graduated arm is adapted to be adjustedinwardly and outwardly to arrange the knife the proper distance from thecenter to cut a washer of the desired diameter, and the relatively fixedactuating member, which engages the feed wheel, is adjustable radiallyof the frame by means of the said perforations.

The knife is yieldably supported in an elevated position by means of acoiled spring 26, disposed on the upper portion of the shank or bodyportion of the knife and in terposed between the upper edge or face ofthe graduated arm and a suitable stop 27 preferably consisting of a pin,which pierces the upper portion of the knife. Any other suitable meansmay be employed for engaging the upper end of the spring with the knife,and when the feeding device is raised by a screw, the springautomatically lifts the knife.

The washer and gasket cutter is adapted to operate on all kinds ofpacking material, and a glass cutter consisting either of a diamond or asteel wheel may be substituted for the knife to enable the device to beemployed for cutting glass.
